Abstract
A signal of bandwidth F.sub.max is unambiguously transmitted over a datalink having a bandwidth less than F.sub.max by subdividing the signal into a plurality of subspectrums and bandshifting the subspectrums greater than the datalink bandwidth to baseband. Each bandshifted subspectrum is uniquely encoded using a different pilot tone which can be detected by the receiver to decode the receive signal and unambiguously recover the narrowband spectrum components.
